what gets a better performance in gamming ??
if u guys have a benchmarch i will apreciate ...
truthfully, you cant go wrong by going with dual channel, its not like it will make your system slower in itself... though there are a few cons against it... it takes up a minimum of 2 dimm slots on your motherboard, and they always have to be even amounts of dimm modules... potentially lessening the total amount of memory you would be able to have installed in your system, which is never a good thing (4x1GB compared to 4x512, etc)... you dont want to be relying on your hdd for virtual memory, because windows ran out of available system memory, which ends up slowing your performance waay down as a result
benchmarks shouldnt be too difficult to find if you google for them... ...when it comes to gaming performance (which is what youre asking about), the gpu is what either makes or breaks decent gaming performance (most every other component in your system is fairly negligable as far as gaming performance impact), and the gpu is more often the bottleneck than anything when you start increasing details and resolutions... so dual channel will not help there (wont increase gpu speed, etc)
i would definetly be more concerned with total system memory amount, than the actual speed and bandwidth of the memory, when it comes to a resource hungry application, such as most current games
